I did a review of the game back in February. Check that out here.
From the campaign:
RE:VERSUS is a 2 or 4 player rummy-inspired card game where players must race against each other to be the first to score 100 points. Watch out for your opponent who will steal your points in part or switch sides and take everything you have.
In the game, there are 2 sides to each face - black and white. You put together 3 cards on your side to score points. The higher the numbers on the cards, the more points you could earn. Your strategy in the game is as personal as you are. You can focus on making big point melds, making lots of melds or rapidly deploy action cards to keep your opponent nervous.
To score the most points and come out victorious, you must be strategic (and get lucky) when and how you lay cards down.
RE:VERSUS is for ages 8 and up and most games take 15-20 minutes.
